Overheating, coolant fluids isnt working , its saying change oil but its full
A fuel pump will not cause overheating, a defective engine thermostat will as well as a leaking heat gasket or low coolant level.
SOURCE: MY CAR IS OVERHEATING BUT NO SMOKE...IT SAYS THAT
The most common overheating problem with the Northstar engine is a blocked purge line. It's job is to purge air out of the cooling system.
There is a small diameter hose coming from near the top of the coolant tank,this is the purge line.
With the engine idling,pull the purge line from the tank,if there is no coolant flow from this small hose,it is blocked and this will cause overheating.If the hose is clear, check for blockage at the nipple on the tank.Or trace the hose back until you find the blockage.The hose goes in to the engine to a crossover and comes out the other side to near the thermostat housing,the blockage may be there.
SOURCE: Overheating and change engine oil ... oil was changed one week ?
it seems like the radiator of your car needs attention. check for coolant level in it, when its cold. if les add some coolant and then see if the problem persists.
--than there are chances of chocking in the coolant pipes, may be they not reached to engine..
--Check the chock,, that it is not turned on.
--May be sum loosing nut in engine.

Check for a burned fusible link under the hood. If you have power at the fuel pump relay, you could have a bad ignition switch or bad oil pressure switch...accordianman

Does the engine crank over with the starter, and did the vehicle not start after changing the fuel filter?
